Abstract

The utility model belongs to a hardware fitting technical field, the name is interior opening dish spring, including dish spring body, dish spring body in the middle of have a mounting hole, from the mounting hole external half be inner ring part, zhonghuan subtotal outer loop part in proper order, the upper surface of inner ring part is less than the upper surface of outer loop part, the lower surface of inner ring part is less than the lower surface of outer loop part, zhonghuan subtotal inner ring part on a plurality of radial first gaps from mounting hole center peripherad evenly distributed have, the inner ring part was run through in first gap, second gap in addition in the middle of adjacent first gap, the second gap be the radial gap from mounting hole center peripherad, the gap do not run through inner ring subtotal outer loop part. Such dish spring has that elasticity capacity is strong, excellent in use effect's advantage, also have the second gap in the middle of adjacent first gap, have and guarantee to use the high advantage of intensity.

Description

Inner opening disc spring

Technical field

This utility model belongs to Hardware fitting technical field, concretely relates to disc spring.

Background technology

Having installing hole in the middle of disc spring, be saucer-like configuration on the whole, it is that high-elastic steel disc is made；In prior art, dish Do not have gap and aperture, such disc spring to have the shortcoming of elasticity capacity difference above spring, have impact on the using effect of disc spring.

Summary of the invention

The shortcoming that the purpose of this utility model is aiming at prior art, it is provided that a kind of elasticity capacity is strong, using effect good Disc spring inner opening disc spring.

The technical solution of the utility model is achieved in that inner opening disc spring, and including disc spring body, described disc spring is originally There is in the middle of body installing hole, be annular inner portion, cyclic moieties and outer ring portion the most successively from installing hole, annular inner portion upper Surface, is characterized in that: described less than the lower surface of outer ring portion less than the upper surface of outer ring portion, the lower surface of annular inner portion Have on cyclic moieties and annular inner portion multiple from installing hole center to periphery equally distributed radial first gap, first seam Gap penetrates annular inner portion.

Saying also have the second gap in the middle of the first adjacent gap further, the second described gap is from installing hole Center is to the radial gap of periphery, and described gap is not through annular inner portion and outer ring portion.

The beneficial effects of the utility model are: such disc spring has the advantage that elasticity capacity is strong, using effect is good；In phase Also have the second gap in the middle of the first adjacent gap, there is the advantage ensureing to use intensity high.

Accompanying drawing explanation

Fig. 1 is this utility model plan structure schematic diagram.

Fig. 2 is the A A cross-sectional view in Fig. 1.

Wherein: 1, installing hole 2, annular inner portion 3, cyclic moieties 4, outer ring portion the 5, first gap 6, second Gap.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is described further.

As shown in Figure 1, 2, inner opening disc spring, including disc spring body, in the middle of described disc spring body, there is installing hole 1, from Installing hole is annular inner portion 2, cyclic moieties 3 and outer ring portion 4 the most successively, and the upper surface of annular inner portion is less than outer ring portion Upper surface, the lower surface of annular inner portion, less than the lower surface of outer ring portion, is characterized in that: described cyclic moieties and internal ring portion Have on Fen multiple from installing hole center to periphery equally distributed radial first gap 5, the first gap penetrates internal ring portion Point.

Saying also have the second gap 6 in the middle of the first adjacent gap further, the second described gap is from installing hole Center is to the radial gap of periphery, and described gap is not through annular inner portion and outer ring portion.

The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model be not limited to this, Any those skilled in the art is in field of the present utility model, and change or the modification made all are contained of the present utility model In the scope of the claims.

Claims

1. inner opening disc spring, including disc spring body, has installing hole, from installing hole the most successively in the middle of described disc spring body Being annular inner portion, cyclic moieties and outer ring portion, the upper surface of annular inner portion is less than the upper surface of outer ring portion, annular inner portion Lower surface, less than the lower surface of outer ring portion, is characterized in that: have multiple from installation on described cyclic moieties and annular inner portion Center, hole is equally distributed radial first gap to periphery, and the first gap penetrates annular inner portion.

Disc spring the most according to claim 1, is characterized in that: also have the second gap in the middle of the first adjacent gap, described The second gap be that described gap is not through annular inner portion and outer portion from installing hole center to the radial gap of periphery Point.
